As shown in Figure 2-1, the MFC (mass flow controller) is composed of a PC board that is integrated with the following sections: • Flow and temperature sensor • Bypass • Electronics • Control valve PC board Control Valve Sensor Gas outlet Gas inlet Base Bypass Figure 2-1. MFC cutaway view 5700512-C Product Overview 2-1 Advanced Energy® When gas flows through the MFC it is split into two streams. A larger stream is routed through the bypass assembly, and a smaller stream that is proportional to the larger stream is routed through the flow sensor. The MFC is designed so that the ratio between these two streams remains constant over the entire measurable flow range of the instrument. The flow sensor measures the flow of the smaller stream which represents the total gas flow through the MFC. The flow sensor consists of a small stainless steel capillary tube with two thermal resistors wound around the outside. Current passes through the thermal resistors that function as heaters to warm the sensor tube. The thermal resistors form part of a bridge circuit that senses the resistors’ resistance balance. When gas is flowing, heat is transferred from the upstream to the downstream thermal resistor. The degree of imbalance is proportional to the rate of the gas flow. The control valve adjusts gas flow through the MFC based on the flow sensor reading and the set point to ensure a stable gas flow from the MFC. For more detailed information regarding the components in the MFC, see “MFC Components” on page 2-2. MFC COMPONENTS The main components of the MFC are the flow sensor, bypass, electronics (bridge, amplifier, and comparator circuits), and valve assemblies. Figure 2-2 illustrates these major components. 2-2 Product Overview 5700512-C Series FC-77X / 77XX, Series FC-78X / 78XX, and Series FC-79X MFCs Figure 2-2. MFC functional block diagram Flow Sensor Assembly The flow sensor consists of a capillary tube wound by two self-heating resistance wires through which electrical current is passed. The resistance wires heat the sensor tube and when gas flows through the flow sensor a temperature differential is produced between the upstream and downstream wires. The temperature change causes a change in resistance which is detected as an electronic signal by the bridge circuit of the electronics assembly. The MFC uses the mass gas flow measurement because the heat exchange between the gas and the self-heating resistance wire depends on the mass flow. When gas is not flowing, heat is distributed evenly over the upstream and downstream wires, therefore the resistance of upstream and downstream wires is equal and the bridge circuit outputs zero. When gas flows, heat is exchanged between the gas and the self-heating resistance wires. The temperature distribution between the upstream and downstream resistance wires changes causing an imbalance. The imbalance of the upstream and downstream temperatures results in a resistance differential that is detectable by the bridge circuit as an electronic signal. The electronic signal represents the mass gas flow. 5700512-C Product Overview 2-3 Advanced Energy® As a result of the techniques of thermal mass flow measurement, gas flow can be measured independently of factors which affect volume and density, such as temperature and pressure. Bypass Assembly The bypass assembly diverts a small stream of incoming gas through the flow sensor and channels the rest through the bypass and toward the valve assembly of the MFC. The bypass assembly design ensures a constant flow ratio between the flow sensor and the larger flow passing through the instrument, making the output signal of the flow sensor proportional to the total (or mass) gas flow. A comparator circuit in the electronics assembly compares the output signal from the flow sensor and the flow set point. The signal created from this comparison drives the control valve until the difference between the set point and the sensor output signal decreases to zero. Electronics Assembly The electronics assembly consists of a bridge circuit, a high resolution analog converter, a valve drive circuit, and an analog I/O. The signal generated by the bridge circuit is amplified and fed into the analog converter which outputs this signal into the CPU (central processing unit). The CPU compares the set point signal to the sensor reading to generate a signal to drive the control valve. Valve Assembly The valve assembly consists of a normally closed or normally open, solenoid control valve. 2-4 Product Overview 5700512-C Series FC-77X / 77XX, Series FC-78X / 78XX, and Series FC-79X MFCs Chapter 3 Installation and Operation PREPARING TO INSTALL THE UNIT The following sections provide information that you need to understand before installing the MFC. Installation Requirements Install the MFC according to the following requirements. Operating and maintenance personnel must receive proper training before installing, troubleshooting, or maintaining this equipment. • Do not use this product for medical or life-support purposes. • Use the appropriate tube size for the MFC fitting.

Preparing the Installation Site Before installing the MFC, thoroughly clean, dry, and purge all piping associated with the entire flow control system (in accordance with your company’s procedures). The MFC control valve is not capable of completely shutting off gas flow. You must install another shut off valve downstream of the MFC to completely stop gas flow. Unpacking the MFC The MFC is manufactured in a cleanroom environment and delivered in contamination-free packages. Unpack MFC products in a cleanroom. Unpack and inspect the MFC carefully, looking for obvious physical damage. If no damage is apparent, locate and save all documentation, and then proceed with the installation procedures. If you do see signs of shipping damage, contact Aera, an Advanced Energy company, and the carrier immediately (see “AE Global Services” on page 5-6 for contact information). Save the shipping container for submitting necessary claims to the carrier. Save any undamaged shipping materials in the event you must ship the MFC in the future. For more information on shipping an MFC, see “Packing an MFC for Shipping” on page 5-10. Positioning the MFC Position the MFC so the gas flow is in the direction of the arrow stamped on the MFC base. The MFC can be mounted in any position, but the zero point may shift if the MFC is mounted in a non-vertical position. Adjust the zero point in the intended mounting position before running the MFC (see “Zeroing the MFC” on page 3-9 for more information). 5700512-C Installation and Operation 3-3 Advanced Energy® Mounting the MFC Look to the following information to correctly mount the MFC. Note: If you are using an MFC with IGS connections, you must make the mechanical connections before mounting the MFC. See “Making the Mechanical Connections” on page 3-4 for more information. Note: The MFC may be retrofitted into any system because it has been manufactured for drop-in replacement for all existing MFCs and is backward compatibility with all older analog MFCs. To Mount the MFC: 1. Match the mounting holes on the bottom of the MFC with those on the mounting surface. 2. Using two #8-32 UNC-2B screws mount the MFC. Ensure it is securely attached and will resist vibration from external sources. See “MFC Dimensions” on page 6-33 for dimensional drawings of the MFC, as well as the specifications of the MFC mounting footprint. Making the Mechanical Connections To make the mechanical connections for the MFC, connect the inlet and outlet fittings of the MFC to the gas supply line. Depending on the fitting type, use one of the following procedures to connect the MFC. Note: See “Model Specifications” on page 6-1 for more information about your fitting type. To Make VCR Fitting Connections: 1. Verify the MFC is correctly mounted (see “Mounting the MFC” on page 3-4). 2. Inspect the tubing, ferrules, and fittings for dirt, dust, contamination, or damage. If necessary, replace damaged components and clean the tubing, ferrules, and fittings in accordance with your company’s procedures. 3. Insert associated tubing until it rests flush against the shoulder of the fitting. 4. Tighten nut to finger tight and then 1/8 of a turn past finger tight. To Make IGS Connections: 1. Inspect the mounting blocks for dirt, dust, contamination, or damage. If necessary, replace damaged components and fittings in accordance with your company’s procedures. 2. Insert appropriate metal seals for your seal type. Note: Metal seals are not included with the MFC. 3-4 Installation and Operation 5700512-C Series FC-77X / 77XX, Series FC-78X / 78XX, and Series FC-79X MFCs 3. Mount the MFC and tighten screws according to IGS torque specifications (see “Mounting the MFC” on page 3-4). Making the Electrical Connection Connect the system to the MFC using an appropriate mating connector and cable. For electrical connector pin and signal information, see Chapter 4, “I/O Connections and Communication.” Note: If possible, securely fasten the connector with jack-post screws to the MFC to prevent the connector from vibrating loose. Signals at this I/O port can be sensitive to electrical noise. Take standard preventative measures against electromagnetic interference (EMI), including using shielded cable. POWER SUPPLY REQUIREMENTS For specific power supply requirements, see the specifications for your MFC model in “Model Specifications” on page 6-1. Note: The power supply used with the MFC must be sufficient to handle the larger current demand during operation. Additionally, the ripple voltage of the power supply should be less than 20 mV. If needed, Aera recommends using the following Aera power supplies for use with Aera MFCs: • PS94UA (For use with up to 4 MFCs) • PS76DA (For use with up to 6 MFCs) • PS74DA (For use with up to 4 MFCs) GROUND CONNECTIONS The MFC employs both signal and power commons. Proper grounding of these common leads is essential for the MFC to operate accurately and safely. Improper grounding practices may result in inaccurate actual and indicated flow. Follow all appropriate industry and local practices and standards in making these connections. Note: For electrical connector pin and signal information, see Chapter 4, “I/O Connections and Communication.” 5700512-C Installation and Operation 3-5 Advanced Energy® Testing the System for Leaks Do not use liquid leak detectors to leak test connections. They may damage the MFC. After installing the MFC in your system, you should test the leak integrity of the gas connections with a helium leak detector. Note: MFCs equipped with a normally closed control valve should be leak tested with the valve open (by providing a set point voltage to the MFC). For more information about setting the set point voltage, see Chapter 4, “I/O Connections and Communication.” CONNECTING THE MFC TO PERIPHERAL EQUIPMENT The following illustrations provide guidance for connecting a MFC to peripheral equipment.

Do not remove the MFC cover. First-Time Operation The first time you operate the MFC: 1. Ensure that you have installed the MFC properly by following the procedures in “Installing the Unit” on page 3-2. 2. After energizing the MFC (turning on power) through the appropriate communications interface, allow the MFC to warm up for at least 15 minutes before supplying gas to the MFC. If you observe deviation in the zero output, perform a zero-point adjustment (see “Zeroing the MFC” on page 3-9). 3. When using the MFC with vapors at room temperature, set the supply pressure at the minimum value capable of securing the full-scale flow rate to avoid liquid recondensation in the pipes. Be sure to maintain stable temperature for all pipes. Zeroing the MFC Look to the following information to adjust the MFC to the zero point. Note: Contamination can negatively affect proper flow rate control and measurement, despite zero point adjustment. Before Zeroing the MFC, Review the Following: • Make sure that your MFC has a zero-point adjustment hole. To identify this hole, see Figure 3-4 on page 3-10. If your model does not have this hole, you can not adjust the zero point. In this situation, contact AE Global Services (see “AE Global Services” on page 5-6). • The MFC can be mounted in any position. However, if the MFC is in a vertical position, thermal siphoning can occur with a gas that has a molecular weight that is 140 or less, which may cause the zero point to shift. Make sure to adjust the zero point in the intended mounting position and with pressured service gas. • Adjust the zero point at the service operating temperature. Temperature deviations, even within the specified range of operating temperatures, may cause the zero point to shift. 5700512-C Installation and Operation 3-9 Advanced Energy® To Adjust the MFC Zero Point: 1. Make sure that the MFC has reached ambient temperature. 2. Energize the MFC, then wait at least 15 minutes. During this time, make sure that the ambient temperature remains constant and that the output stabilizes. 3. Close the shut-off valves upstream and downstream of the MFC to ensure that there is no gas flow. 4. For normally closed MFCs set the set point signal to 0 V. For normally open MFCs, set the set point signal to 5 V. For more information on the set point command, see Chapter 4, “I/O Connections and Communication.” 5. Use a small, flat head screw driver to make the zero-point adjustment as shown in Figure 3-4. Figure 3-4. MFC zero point adjustment 3-10 Installation and Operation 5700512-C Series FC-77X / 77XX, Series FC-78X / 78XX, and Series FC-79X MFCs MAINTENANCE Recalibration and repair should be performed by Advanced Energy. See “AE Global Services” on page 5-6 for contact information. Note: Removal of an MFC should be done only after adequate purging with a nonreactive gas such as nitrogen gas (N2). You should follow your company procedures for removing gas line components. Reactive gas calibrated MFCs may receive severe contamination or corrosion from exposure to air or moisture. Check plumbing for leaks, and purge thoroughly with dry nitrogen before operating or disconnecting from the system. STORAGE Observe the following requirements when placing an MFC in storage: • Temperature between 5ºC (41ºF) and 45ºC (113ºF) • Relative humidity less than 60% Additionally, prevent any mechanical impact or corrosion. 5700512-C Installation and Operation 3-11 Advanced Energy® 3-12 Installation and Operation 5700512-C Series FC-77X / 77XX, Series FC-78X / 78XX, and Series FC-79X MFCs Chapter 4 I/O Connections and Communication The following sections provide information on the MFC’s electrical connectors and communication interfaces for MFC control, read back, and alarm indications. 20-PIN CARD EDGE CONNECTOR AND 20PIN HONDA CONNECTOR Card Edge Connector Figure 4-1 shows the pin names on the card edge connector. 1 A 2 B 3 C 4 D 5 E 6 F \ \ 8 J 9 K 10 L Figure 4-1. 20-pin card-edge connector 5700512-C I/O Connections and Communication 4-1 Advanced Energy® Honda Connector Figure 4-2 shows the pin numbers on the 20-pin Honda connector. 11 1 12 2 13 3 14 4 15 5 16 6 17 7 18 8 19 9 20 10 Figure 4-2. 20-pin Honda connector 20-Pin Connector Signal Descriptions Table 4-1 provides the pin and signal descriptions for the 20-pin card-edge connector and the 20-pin Honda connector.

Alarm Output (Error Detection) Signals Not all MFC models provide these signals. To see if your model provides alarm output signals see the specifications for the MFC model in question (see “Model Specifications” on page 6-1). For signal descriptions, see Chapter 4, “I/O Connections and Communication.” FC-77X and FC-77XX MFCs provide error detection as a standard feature. The function is an option on some other models. For MFCs with the error detection feature, the MFC provides alarm output if it detects a difference between the flow rate set point and the actual flow rate for longer than eight seconds. 5700512-C I/O Connections and Communication 4-7 Advanced Energy® As shown in Figure 4-4, ALARM H and ALARM L are connection terminals for the open collector that is isolated with the photocoupler. To use the terminals, apply appropriate power, as shown in the illustration. Use the ALARM ON/OFF signal to reset the signal. Note: If no gas is being supplied, but the MFC has a nonzero set point, the MFC will report an error (because the flow rate does not match the set point). Figure 4-4. Alarm connection Control Valve Purge Function Signals The control valve purge function allows you to completely open the control valve and purge gas at many times the MFC full-scale flow rate. This function is particularly useful for purging gas when using MFCs with a low full-scale flow rate or for leak checking. The settings for opening/closing the control valve vary with the connector type and, in some cases, with whether the MFC is normally open or normally closed. For most applications, this signal is not connected. The following illustrations show the connection and the internal MFC wiring, for the purge function signals on all connectors. 4-8 I/O Connections and Communication 5700512-C Series FC-77X / 77XX, Series FC-78X / 78XX, and Series FC-79X MFCs CARD EDGE PURGE FUNCTION SIGNALS For the card edge connector, MFCs with normally open and normally closed valves require inverse connections. Be sure to connect the signal properly. (To check whether an MFC is normally closed or normally open, see “Model Numbers for this Manual” on page 1-1.) Figure 4-5 shows the connections. Figure 4-6 and Figure 4-7 show the internal circuitry for normally open and normally closed MFCs, respectively. To disengage this function, disconnect the MFC terminal. Figure 4-5.

Calibration References In order to ensure MFC cleanliness, AE may use a surrogate calibration gas rather than the gas indicated on the label. The calibration ambient temperature is 22ºC. (If the MFC requires a different ambient calibration temperature, that temperature is indicated on the MFC label.) Note: The calibration gas and its conversion factors are subject to change due to technological innovation or changes in environmental regulations. Table 6-37. Calibration references Description Specification Calibration method Primary, secondary, or rate of rise of N2 (or other surrogate gas) Reference conditions 0ºC / 760 Torr per SEMI E12-96 Traceablity All calibrations are traceable to Japan standards and/or United States standards (NIST) FLOW INDICATION Flow rate is indicated by standard cubic centimeters per minute (sccm), cubic centimeters per minute (ccm), standard liters per minute (slm), and liters per minute (lm) as follows: • For sccm and slm, gas flow rates at 0ºC, 101.3 kPa • For ccm and lm, gas flow rate at customer-defined temperature, 101.3 kPa Note: Unless otherwise noted, sccm and slm are used for calibration. 5700512-C Specifications and Reference Information 6-39 Advanced Energy® Product Label The MFC product label displays the following: model number, serial number, calibration gas, surface treatment, and full-scale flow.
